Overview
Assembly brings together stamped, machined, welded and sourced components into a finished part or sub-assembly ahead of packaging and shipment. For lock components and custom OEM parts in particular, assembly may include mechanical fastening, press-fitting or the integration of purchased hardware such as springs and pins. Assembly sequence and inspection points are defined per part based on the bill of materials and drawing requirements.
Advantages
- Single-source integration from stamped part to finished assembly
- Assembly sequence matched to bill of materials and drawing
- Coordinated with in-process and final inspection
Supported Materials
- Assembly of metal components and standard hardware (springs, pins, fasteners)
Equipment & Process Range
Assembly method (manual, fixture-assisted or automated) is confirmed per part based on volume and complexity.
Specific equipment models, tonnage and unit counts are confirmed by engineering per project rather than published as general figures.
Workflow
Component Kitting
Stamped, machined and sourced components are kitted according to the bill of materials.
Assembly
Components are assembled in sequence using fixtures or fastening methods specified for the part.
Functional Check
Assembled parts are checked for fit and function against drawing requirements.
Packaging Preparation
Finished assemblies are prepared for packaging and shipment.
Quality Controls
- Fit and function checks
- Sampling inspection of assembled units
- Bill-of-materials verification

Frequently Asked Questions
What file formats are accepted for a quote submission?
PDF, DWG, DXF, STEP, JPG and PNG files are accepted. Multiple files should be uploaded individually rather than as a compressed archive; each file must be 20MB or smaller.
Does YO JYI assemble finished sub-assemblies?
Yes. Components can be kitted and assembled into finished sub-assemblies, including integration of standard hardware such as springs and pins, prior to packaging.
What information do I need to provide for a metal stamping quote?
To request a quote, provide your part drawing (PDF, DWG, DXF or STEP), target quantity, material preference and any surface finish requirement. Submitting a drawing lets engineering confirm feasibility, tolerances and lead time for your specific part.
